If I create a branch from a project's trunk, then can I merge revisions both
from the trunk->branch and from the branch->trunk?
The purpose is for revisions to be committed on both the trunk and the
branch, and they'll be merged to the other without either the trunk or
branch ending so that development can continue on both.
Am I right in that --reintegrate signals the end of a branch, so I wouldn't
use that here?
